I just uninstalled and reinstalled the program, same thing! I am so frustrated and now I have to redo all my letters, billings etc because I did this reinstallation. Grrr! Thanks for trying to help, I am now at the mercy of someone else at Intuit Tech Support! I wish there was something else I could do, I am not a novice with this program as I have been a customer since 1995!!! Never, ever, have I had this kind of problem.
So...after calling tech support again, this time the problem has been resolved. After entering the W-2G information, then go up to the W-2G summary page, hit that. then go back to Schedule 1 and tax payment worksheet, click on magnifying glass, multiple times cuz it takes you to different worksheets, when done, the income and withholdings finally flow through. Hope this helps other preparers who are entering gambling income. This will be fixed with the January 26th update, so I was told.
